CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 364,943, dated June 14,1887.

Application filed March 29, 1887 Serial No. 232,886. (No model.)

To aZZ whom it may concern.-

Be it known that we, NICHOLAS P. LEHR and J osErH W. Lnnn, citizens ofthe United States of America, residing at Fremont, in the county ofSaudusky and State of Ohio, have invented certain new and usefulImprovements in Cultivators, Ot'which the following is a specification,reference being bad therein to the accompanying drawings.

This invention pertains to certain new and useful improvements ineultivators; and it consistsin the detailed construction, combina tion,and arrangement of the parts, substantially as hereinafter fully setforth,and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view ofourinvention, and Fig. 2 is an enlarged detail thereof.

The object of this invention is, first, to provide means for regulatingthe tension of the spring secured to the plow-standards according to thedepth of penetration desired to be obtained, and, secondly, for theemployment of a central supplementary plow standard and shovel forattaining a perfect central draft.

In carrying out our invention to accomplish the above object, we secureto the upper horizontal part of a cultivator axle or frame, A, the uppersleeved ends oftheswinging hangers a, composed each of a single, double,or slotted bar, as may be desired, said ends of hangers being held asagainst lateral movement by meansof thumb screws passed through suitablecollars, as shown. On the lower bolt-like end of each of these hangersis secured a clevis, a, to which is attached the forward united ends ofcultivator-shovel standards b, which will be referred to on.

B B are sleeves slipped on the approximately-vertical portions of thehangers e,aud held at any desired point thereon by set screws 2),working through the sides of said sleeves and bearing against the saidhangers, or said sleeves can be secured by means of clamps or small camsin lieu of setserews, if preferred. To each of these sleeves isconnected one end of a chain, 0, connected at its other end to acoil-spring, 0, attached to a cross-bar, (1, secured between any two ofthe shovel-standards, as shown. A horizontally-disposed cross-bar, D,issecured on the bolt-1ike ends of the hangfarth er ers a, through anaperture in the body of the cleviscs a, said bar having an aperture ineach end, through which said bolt-like ends are passed. To the center ofthis horizontally-disposed bar D is secured, by a joint-like connection,the forward end of a central cultivatorshovel standard or beam, D, whichis additionally secured or held in position by a crossbar, I)", attachedthereto, and to the cultivator shovel beams, as shown. By thisconstruction and disposition of partsa perfect central draftis attainedin connection with the two or three shovelstandards disposed on eitherside of said central standard, I).

From what has gone before itwill be seen that by means of thethumbscrews of the sleeves B the latter can be adjusted and secured atany desired point on the hangers,ac cording as it may be desired toregulate the depth of penetration of the cultivator shovels bytightening orloosening the tension of the coil-springs attached to saidstandards.

Having thus fully described our invention, what we claim, and desire tosecure by Letters Patent, is-

1. The combinatiomwith the vertical hang ers, the cultivator-shovelbeams seen red thereto, and the springs connected to said beams, of

the adjustable sleeves fitted on said hangers, having projecting hookson one side thereof, and the set-screws workingin the opposite sides ofsaid sleeves and bearing agai nst said hangers, substantially as shownand described.

2. The combinatiomwith the vertical haugers, the cultivator-shovelbeams, andthe clevises secured on said hangers, of thehorizontallydisposed cross-bar secured on the lower ends of said hangersin apertures of said clevises, and the central cultivator shovelstandard having a joint-like connection with said crossbar,substantially as shown and described, said central standard beingadditionally held in position by a second cross-bar, as shown.

In testimony whereof we affix our signatures in presence of twowitnesses.
